Why is a depletion of the ozone layer harmful? (2 points)

Select one:
a. It increases chlorofluorocarbons (CFCs).
b. It allows increased amounts of UV radiation to reach Earth's surface.
c. It increases crop yields.
d. It contaminates ground water.

b.

Explanation:

As the ozone layer is essential for nullifying the rays of the sun, without it there would be much more UV radiation.

chemical properties are the characteristic of matter which can only be observed by changing the chemical identity of a sample like flammability reactivity and toxicity.

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.

hope this .
